It may be urged that different circumstances might have suggested this profession to me at a later date. It is probable; but then I should have had no time for it. Would any workman, artisan, or tradesman give up a certainty, however slight it may be, to yield to a passion which would be surely regarded as a mania? Hence my irresistible penchant for the mysterious could only be followed at this precise period of my life. How often since have I blessed this providential error, without which I should have probably vegetated as a country watchmaker! My life would have been spent in gentle monotony; I should have been spared many sufferings, emotions, and shocks: but, on the other hand, what lively sensations, what profound delight would have been sacrificed! I was eagerly devouring every line of the magic book which described the astounding tricks; my head was aglow, and I at times gave way to thoughts which plunged me in ecstasy. The author gave a very plain explanation of his tricks; still, he committed the error of supposing his readers possessed of the necessary skill to perform them. Now, I was entirely deficient in this skill, and though most desirous of acquiring it, I found nothing in the book to indicate the means. I was in the position of a man who attempts to copy a picture without possessing the slightest notion of drawing and painting. In the absence of a professor to instruct me, I was compelled to create the principles of the science I wished to study. In the first place, I recognized the fundamental principle of sleight-of- hand, that the organs performing the principal part are the sight and touch. I saw that, in order to attain any degree of perfection, the professor must develop these organs to their fullest extent--for, in his exhibitions, he must be able to see everything that takes place around him at half a glance, and execute his deceptions with unfailing dexterity. I had been often struck by the ease with which pianists can read and perform at sight the most difficult pieces. I saw that, by practice, it would be possible to create a certainty of perception and facility of touch, rendering it easy for the artist to attend to several things simultaneously, while his hands were busy employed with some complicated task. This faculty I wished to acquire and apply to sleight-of-hand; still, as music could not afford me the necessary elements, I had recourse to the juggler's art, in which I hoped to meet with an analogous result.
